The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.
Traction control system
“AUTO LSD” system
If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no l onger operate. In this
case, immediately stop your vehicle at a
safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At the time, the slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
it is no problem to continue driving.) The
system will be automatically restored after
a short time and the slip indicator light
goes off.XS17010a
TRACTION CONTROL OFF MODE
(two wheel drive mode only)
When getting the vehicle out of mud or
newly fallen snow, etc., it may be bene-
ficial to turn off the traction control
system. This system that controls en-
gine performance interferes with the
process of freeing rear wheels.
To turn off: Briefly push the “VSC OFF”
switch.
The “AUTO LSD” and slip indicator lights
will come on.
The vehicle stability control system is al-
ways activated, even if the traction control
system is turned off. To turn on: Briefly push the “VSC OFF”
switch once again.
The “AUTO LSD” and slip indicator lights
will go off.
If the engine is turned off while the
“AUTO LSD” and slip indicator lights are
on and then restarted, the indicator lights
will turn off automatically.
When you push and hold the “VSC OFF”
switch for 3 seconds or more with the
vehicle stopped, turn off the vehicle stabil-
ity control system. See “Vehicle stability
control system” on page 248 in this Sec-
tion.
“AUTO LSD” and slip indicator lights come
on for a few seconds when the ignition
switch is turned to the “ON” position. If
the indicator lights do not come on when
the ignition switch is turned to the “ON”
position, contact your Toyota dealer.
CAUTION
Do not drive with the traction control
system continuously turned off.

does not work. However, if the brakes
operate normally when applied, it is no
problem to continue your driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition switch is turned to the
“ON” position.
The warning light remains on after the

The “AUTO LSD” system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system should be used only when
wheel spinning occurs in a ditch or
rough surface.
This system is effective in case one of
the rear wheels is spinning.
